Question

Acer AOD255E CMOS Battery ... ???

by Apr 1, 2015 3:33AM PDT

Hi,

It seems I have yet another problem (nothing is ever easy) with the Acer D255E/PAV70 motherboard...I need to change the CMOS battery...I have been to so many sites and googled in order to find out which battery I need but all to no avail...many laptops use the 2032 battery but this is not the same as the battery on this motherboard is smaller...does anybody know which type of CMOS battery I can replace this with please ?

I can`t see a facility to upload pictures of the battery...it is slightly smaller than a 5p piece.

Hope somebody can help,

Thanks,

It looks to be soldered down.

The CMOS battery is soldered (attached) to the board. Your better tech can change that. Some techs are lost but it's a simple matter of two wires. If your tech is lost, find another.

Battery measurements

If you measure the dimensions of the battery you will find the code.

An example is 2032 - this refers to 20mm diameter and 3.2mm thick.

1616 means 16mm diameter and 1.6mm thick and so on.

So if you measure the battery you have you will find the code of the battery you need.

That gets you the battery size.

But for this model it has solder tabs on the battery. Your every day electronics tech should be able to run 2 wires off to some small space to shoehorn in some cr2032 with solder tabs. For this we can make do and it will work for 5 or more years.
